Sha’at Kosher

The time of fitness is the time when a sacrificial animal is fit to be offered or eaten. For
example, a lamb born healthy that later became disqualified had a time of fitness,
whereas a lamb born with a defect never had one, since animals with defects may not
be offered as sacrifices

Matirim

Permitters are the actions, such as the sprinkling of the animal’s blood on the altar, that
allow a sacrifice to be eaten.

Dachui

An unfit sacrifice is a sacrificial animal that cannot be offered due to having a psul (disqualifying defect) either when its owner dedicated it as a sacrifice or at any point from then until the time that it was supposed to be sacrificed, even if that psul no longer exists. 

Melikah

Pinching is to sacrificial birds as shchitah is to sacrificial animals. The kohen holds the bird in one hand, and, using that same hand, cuts the bird’s head adjacent to its nape with his fingernail. This is only for birds that are to be sacrificed. Birds to be eaten as chulin (not as sacrifices) are slaughtered like other animals by having their necks cut with a knife.

Emurim

The sacrificial portions are the internal organs of the sacrificial animal that the kohen
offers on the altar.

Yotzeh

Yotzeh is a sacrifice or parts of a sacrifice (its limbs or blood) that were taken out of the area where they’re supposed to be sacrificed or eaten. This act disqualifies it from being sacrificed and eaten, though is not punishable by karet.

LiMkomo Chutz

Outside its place – if, during one or more of the four acts of worship, the kohen has the thought that he intends to sacrifice or eat the animal outside the place where doing so is permitted (either Jerusalem or the Beit Mikdash depending on the sacrifice’s level of holiness), this intention disqualifies the animal from being sacrificed and eaten, although it is not punishable by karet.

Notar

Notar is a sacrifice or part of a sacrifice left over after the permitted window of time for eating it has passed. It is forbidden to eat notar, and one who does is punished by karet.

Pigul

Pigul is a thought that the kohen has during one or more of the four acts of worship that he intends to eat or sacrifice the animal after the permitted window of time. This intention is called a “pigul thought,” and makes eating that sacrifice forbidden and punishable by karet.

Lishma

For its own sake – Throughout the sacrificial process, the kohen must actively keep in mind that he is sacrificing the animal for the sake of the person who brought it, and the specific type of sacrifice. If, during one of the four acts of worship, the kohen has a thought “not for its own sake,” that is, if he sacrifices the animal with a different intention (e.g. he thought of the sin-offering as a guilt-offering while slaughtering it), this disqualifies the sacrifice.
